''Noctiluca scintillans'', commonly known as the Sea Sparkle, and also published as ''Noctiluca miliaris'', is a free-living non-parasitic marine-dwelling species of dinoflagellate that exhibits bioluminescence when disturbed (popularly known as mareel). Its bioluminescence is produced throughout the cytoplasm of this single-celled protist, by a luciferin-luciferase reaction in thousands of spherically shaped organelles, called scintillons. Nonluminescent populations within the genus Noctiluca lack these scintillons. ==Diet==
''N. scintillans'' is a heterotroph (non-photosynthetic) that engulfs by phagocytosis food which includes plankton, diatoms, other dinoflagellates, fish eggs and bacteria. Diatoms are often found in the vacuoles (internal membrane-bound storage compartments) within these single-celled creatures. These green non-feeding symbioses can grow photoautotrophically for generations.〔Saito, Haruna, Ken Furuya & Thaithaworn Lirdwitayarpasit, 2006. Photoautotrophic growth of ''Noctiluca scintillans'' with the endosymbiont ''Pedinomonas noctilucae''. ''Plankton & Benthos Research'' 1: 97–101〕 The diatom ''Thalassiosira sp.'' has been noted in the literature as a favored food source of these organisms.
